Answer:
The probability is 0.9
Step-by-step explanation:
We start by calculating the density function
That will be;
f(x) = 1/(b-a)
b and a are the extremes
from the question,
a = 15
b = 65
So f(x)
= 1/(65-15) = 1/50 = 0.02
The probability we want to calculate is;
P( x > 20)
The termination point is 65
So the probability will be
(65-20) * 0.02
= 0.9
Answer:
x = 4
Step-by-step explanation:
((((2•(x4))-(7•(x3)))-2x2)-7x)-4 = 0

Answer:
The coefficient of variation (CV)= 9.83
Step-by-step explanation:
look at the attachment above ☝️
They are not simpler because they do not have the same angles
To find the inverse of a function, replace the variable "x" with "y". Also replace "f(x)" with just "x". Solve this equation for y.
f(x) =2/3x+10
x=2/3y+10
Subtract 10 from both sides:
x-10=2/3y
Multiply both sides by "3/2":
(3/2)(x-10)=y
The inverse function is: f^-1(x)=3/2x- 15
